Review: Great fit for 2” flush valve - Perfect fit for 2” cistern outlets. Added a fat worm of Plumbers Mait and no leaks.
Review: Does the job perfectly - I'd had problems for some time with my Twfords close coupling toilet. I'd already purchased a new flush valve which helped in part but I was still having issues with a leak as none of the donuts I'd previously bought, whether rubber or foam did the job. They were all too bulky. This is perfect. No more leak, no gaps between the cistern and the bowl. I was going to purchase another for the downstairs toilet which was also leaking. However, it transpires fixing the upstairs toilet sorted the downstairs toilet (as the piping is connected) No leaks upstairs and no dripping downstairs. Win win. I honestly didn't think this would work but I gave it a go because of the price. I'm so glad I did.

### ⭐⭐⭐⭐ No instructions for DIY
*by G***D on 22 January 2024*

Well I used this and another item together, as the water would still splash out. Not the issue with the item in particular, it is just my cistern may need double seal.
